In addition, the mudstoen bears more cover load than that of soil layer, so the effect of pressure upon water freezing temperature and unfrozen water content should be considered (or eliminated).
The formula of water freezing temperature and pressure is as follow:
（MPa） (2-14)
But, the test result by Zhang Lixin (1998) also approved that the freezing temperature of frozen soil increases as the pressure decreases, its gradient is close to -0.075℃/MPa [30].
According to formula 2-14, the water freezing temperature drops 0.1℃ (that is at Tm=273.05K), its pressure needed is 1.397MPa.
Knowing from the calculation [30], the freezing temperature of frozen soil drops 0.1 ℃ and its pressure needed is 1.397MPa.
Both are close quantitatively, and both result, on the one hand, were validated each other, and on the other hand it was illustrated that the freezing temperature drop of frozen soil tempertaure activated by of pressure was caused by the drop of water freezing temperature.
According to the core calculation, in order to obtain the said pressure, the depth of soil body should be over 50 meters. So, the effect of pressure on unfrozen water content is not considered in this paper.
